Smoldering and Flame Resistant Textiles via Conformal Barrier Formation

November 2, 2016
Author(s)
Mauro Zammarano, Shonali Nazare, John R. Shields, Kathleen M. Hoffman, Rick D. Davis
A durable and flexible silicone-based backcoating (halogen and formaldehyde free) is applied to the backside of an otherwise smoldering-prone and flammable fabric. When exposed to fire, cyclic siloxanes (produced by thermal decomposition of the backcoating

Results of barrier fabrics tested in an inverted configuration

August 5, 2015
Author(s)
Rick D. Davis, Shonali Nazare, Szabolcs Matko, William M. Pitts, Mauro Zammarano
The document will be used to facilitate discussions between California Bureau of Electronics and Appliance Repair, Home Furnishings, and Thermal Insulation (CBEARHFTI) and us (Fire Research Division (FRD) at the National Institute of Standards and

Cellulose Nanomaterials: Nanocomposite Imaging using FRET

June 19, 2013
Author(s)
Jeffrey W. Gilman, Mauro Zammarano, Iulia A. Sacui, Jeremiah Woodcock
Cellulose is the most abundant organic polymer on Earth, found in plants (cotton, hemp, wood), marine animals (Tunicate), algae (Valonia) bacteria (Acetobacter xylium) and even amoeba (Dictyostelium discoideum). Critical features of the structural

Nanoparticles in Flame-Retardant Coatings for Flexible Polyurethane Foams: Effects on Flammability and Nanoparticle Release

May 15, 2013
Author(s)
Mauro Zammarano, Rick D. Davis, Yeon S. Kim, Richard H. Harris Jr., Marc R. Nyden, Jeffrey W. Gilman, Nasir M. Uddin
Nanoparticles can effectively reduce polymer flammability; however, the impact of nanoparticles on environmental and health safety is still unclear. The purpose of this study is twofold: (1) to develop and investigate the effect of nanoparticle-rich

Impact of Test and Foam Design on Smoldering

May 14, 2013
Author(s)
Mauro Zammarano, Szabolcs Matko, Rick D. Davis
Smoldering propensity of fabrics used in upholstered furniture can be assessed using foam mockups according to the CPSC proposed regulation. This approach requires a polyurethane flexible foam with reproducible and well- characterized smoldering. The

Thermal and Burning Properties of Poly(lactic acid) Composites Using Cellulose-Based Intumescing Flame Retardants

December 21, 2012
Author(s)
Douglas M. Fox, Srilatha Temburni, Melissa Novy, Laura Flynn, Mauro Zammarano, Yeon S. Kim, Jeffrey W. Gilman, Rick D. Davis
Poly(lactic acid) was flame retarded using cellulose-based intumescing flame retardants. Cellulose was an excellent carbon source in combination with ammonium polyphosphate (APP), exhibiting good thermal stabilities and UL-94 ratings of V-0

Smoldering in Flexible Polyurethane Foams: the Effect of Foam Morphology

December 18, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Li Piin Sung, Douglas M. Fox, Shivani N. Mehta
Smoldering is a self-sustaining heterogeneous oxidation reaction that induces a slow, low temperature, flameless combustion. Flexible polyurethane foams (PUF) are prone to smoldering due to their high air permeability, low density and high specific surface

Standard Operating Procedures for Smolder Ignition Testing of Upholstery Fabrics

December 11, 2012
Author(s)
Rick D. Davis, Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer
This manuscript describes a methodology to measure the influence of an upholstery cover fabric to promote smoldering mass loss of a small-scale mock-up. The primary test metric is total mock-up mass loss after 45 min exposure to the smoldering ignition

Formation of Extended Ionomeric Network by Bulk Polymerization of L,D-lactide with Layered Double Hydroxide

November 22, 2012
Author(s)
Edward D. McCarthy, Mauro Zammarano, Douglas M. Fox, Ryan Nieuwendaal, Yeon S. Kim, P H. Maupin, Paul C. Trulove, Jeffrey W. Gilman
We report the formation of an ionomeric network in a poly(L,D-lactide) hybrid nanocomposite, (PLDLA-HYB) during in-situ melt polymerization of L,D lactide in the presence of magnesium/aluminium layered-double-hydroxide (LDH) without added catalyst. The

Factors Influencing the Smoldering Performance of Polyurethane Foam

September 26, 2012
Author(s)
Mauro Zammarano, Szabolcs Matko, Roland H. Kraemer, Rick D. Davis, Jeffrey W. Gilman, Shivani N. Mehta
The objective of this study was to evaluate whether polyurethane foam (PUF) could be produced as a standard reference material for ultimate use in a standard test intended to ensure the smoldering performance of commercially available upholstered furniture

Ionic Liquid Facilitated Introduction of Functional Materials into Biopolymer Polymer Substrates

August 2, 2012
Author(s)
Shonali Nazare, Jeffrey W. Gilman, Mauro Zammarano, Luke Haverhals, W.Matthew Reichert, Hugh De Long, Paul C. Trulove
In addition to being efficient solvents for biopolymers, several ionic liquids (ILs) have been shown to be effective solvents for synthetic polymers such as meta-aramids, i.e., Nomex ® (1-5). In this report, meta-aramid/cotton composites are generated by
